According to a Mazda press release, the company will field a racing version of the 2014 Mazda6 midsize sedan with a race-tuned SKYACTIV-D diesel engine at the Rolex 24 Hours of Daytona endurance race set for January 23-24, 2013.

According to Mazda North American Operations Motorsports Director John Doonan, the car’s diesel engine is expected to put down more than 400 horsepower on race day despite its basis in a stock SKYACTIV-D engine block and “a very long list of production Mazda parts.

“We have been eager to announce this car for months, but had to wait until the production car was revealed,” Doonan said. “The SpeedSource engineering team, working with the Mazda engineers, have been flat out for months on engine development. We’re happy to report that the engine is meeting the performance targets for both power and endurance.”

The car will run in the Rolex 24’s new Grand-Am GX class against other cars that include the Lotus Evora and models from Ford, Chevrolet, BMW, Audi, Mercedes, Porsche, Scion, Nissan, and Volkswagen, according to a Grand-Am press release.
